Lyman Beecher Sperry (1841-1923), physician, lecturer, and author, was the discoverer of Sperry Glacier. Sperry Glacier, Sperry Glacier Basin, and Sperry Chalets are named in his honor. During the summers of 1894-1906, Dr. Sperry camped, climbed, and explored the Montana Rockies, particularly in the area set aside by Congress in 1910 as Glacier National Park. This photograph, taken in 1904 at some unspecified location in the Park area, was by G.H. Dean, student of Dr. Sperry's, who accompanied him on the 1904 trip. Photo no. 6274 from the archives of Glacier National Park, courtesy of U.S. National Park Service. Published as Figure 11, U.S. Geological Survey Professional Paper 1180.
